Ames test, n. Med.|ˈeɪmz ˌtɛst|
[Named after Bruce N. Ames (b. 1928), U.S. biochemist, who devised it.]
A test for mutagenic activity in which the effect of a substance in vitro is observed on certain bacteria in which mutations are readily detected.
1976New Scientist 22 Jan. 168/1 Currently a number of test systems are being developed for detecting possible carcinogens, and one of them in particular—the so-called Ames test—seems just about ready for limited application at least. 1979Nature 8 Nov. 134/1 The invaluable ‘Ames test’ (in reality a mini-battery of tests using bacteria as the test organisms) permits rapid bioassay of chemicals, or their reactive in vitro metabolites, for mutagenic activity. 1984McGraw-Hill Yearbk. Sci. & Technol. 1985 288/1 The Ames test has proved to be about 85{pcnt} accurate in detecting certain classes of chemical carcinogens as mutagens and in predicting that a nonmutagenic compound is noncarcinogenic. |
